News

AMD quietly releases ultra low power APUs

Sep 27, 2012: The launch of AMD "Trinity" mobile lineup back in May included two low- and ultra-low voltage microprocessors. Featuring only 25 Watt or lower Thermal Design Power, new chips were supposedly to be cheaper than Intel's ULV offerings. A quick look at current prices shows that AMD thin-and-light notebooks are indeed less expensive than Intel-based ultrabooks, although this partially can be explained by more stringent Ultrabook requirements, such as notebook's height and battery life.

AMD A4-4355M and A8-4555M APUs surface in Lenovo notebook

Sep 07, 2012: Last week at IFA electronics show in Berlin, Lenovo announced new IdeaPad notebooks, including three S series models: S300, S400, and S405. The S300 and S400 laptops will be based on Intel ULV CPUs, whereas the S405 will be shipped with three ultra low voltage AMD APUs with "Trinity" core. The most interesting part is that two out of three processors are not yet released. These are A4-4355M and A8-4555M.
